The market demand for a particular good in city A is given by Q(A) = 32 ? 0.5P (for P ? 64). This market is served by a single firm (monopoly) whose marginal cost of production is 4 dollars per unit (so total cost of producing Q units is 4Q).

(a) Find the equation for the firm’s marginal revenue function. Draw the demand, marginal cost and marginal revenue curves on one graph.

(b) What are the profit-maximizing price and quantity for the monopolist?

(c) Calculate the monopoly profit and mark-up in city A.

(d) What is consumer surplus in this market? How large is the deadweight loss resulting from monopoly pricing?

Expert Solution

Market demand function is Q = 32 – 0.5P or inverse demand function is 0.5P = 32 – Q or P = 64 – 2Q

a) Now we have P = 64 – 2Q. Total revenue function is TR = 64Q – 2Q^2. Marginal revenue is the derivative of TR so MR = 64 – 4Q

b) Monopolist equates MR = MC

64 – 4Q = 4

Q = 60/4 = 15 units and so monopolist charges a price of 64 – 2*15 = $34 per unit.

c) Profit = TR – TC = 15*34 – 4*15 = 15*30 = $450. Mark up = (P – MC)/P = (34 – 4)/34 = 0.88

d) CS = 0.5*(Max price – current price)*current qty = 0.5*(64 – 34)*15 = $225

DWL = 0.5*(34 – 4)*(30 – 15) = $225

The market supply is given by P = 20 + Q. The market demand for good X is given by P = 100 - 2Q - PZ. PZ is the price of a related good Z. Find the market equilibrium for good X when PZ equals 38; denote the equilibrium as P1 and Q1. Find the market equilibrium for good X when PZ equals 44; denote the equilibrium as P2 and Q2. Using the midpoint method, the price elasticity of...

The inverse market demand for a homogeneous good is given by p = 1 – Q,...

The inverse market demand for a homogeneous good is given by p = 1 – Q, where p denotes the price and Q denotes the total quantity of the good. The good is supplied by three quantity-setting firms (Firm 1, Firm 2, and Firm 3) competing à la Cournot, each producing at a constant marginal cost equal to c > 0. a) Derive the best reply of Firm 1. b) Compute the Cournot-Nash equilibrium quantity and profits of Firm 1....

The market demand function for a good is given by Q = D(p) = 800 − 50p. For each firm that produces the good the total cost function is TC(Q) = 4Q+( Q2/2) . Recall that this means that the marginal cost is MC(Q) = 4 + Q. Assume that firms are price takers. In the short run (with 100 firms), and assume that the government imposes a tax of $3 per unit. (a) What would be the new equilibrium...

The inverse demand function in a market is given by p=32-Q where Q is the aggregate quantity produced.

The inverse demand function in a market is given by p=32-Q where Q is the aggregate quantity produced. The market has 3 identical firms with marginal and average costs of 8. These firms engage in Cournot competition. a) How much output does each firm produce? b) What is the equilibrium price in the market? c) How much profit does each firm make? d) Consider a merger between two firms. Assuming that due to efficiency gains from the merger,...

Consider a market for a good characterized by an inverse market demand P(Q) = 200−Q. There are two firms, firm 1 and firm 2, which produce a homogeneous output with a cost function C(q) =q2+ 2q+ 10. 1. What are the profits that each firm makes in this market? 2. Suppose an advertising consultant approaches firm 1 and offers to increase consumers’ value for the good by $10. He offers this in exchange for payment of $200. Should the firm...
